A radiator comprises a heat conduction base (10) and a plurality of primary radiating strips (20). Each primary radiating strip (20) is disposed on a top surface (12) of the heat conduction base (10) and is perpendicular to the top surface (12) of the heat conduction base (10). The primary radiating strips (20) are arranged in a circumferential direction and surround to form a column-shaped convection channel (27), a heat convection channel (25) is formed between every two adjacent primary radiating strips (20), and each heat convection channel (25) is communicated with the column-shaped convection channel (27). The radiator can carry out radiation in a heat conduction mode, a heat convection mode, and a heat radiation mode at the same time. The radiator has rapid and good radiating effect, is especially suitable for radiation of large-power chips, and saves materials and reduces the cost. |
